I was assisting in troubleshooting problems doing SIP Trunking to
sipXecs. When accessing the service over public internet, we require
digest authentication. When a User name for SIP authentication is
configured and the "Use default asserted identity" box is checked, the
value in the "User name" field gets put into the user part of the From
URI and P-Asserted-Identity URI. This looks wrong. The "User name"
field appears to be overloaded, being used for both SIP credentials
and subscriber identification. Authentication credentials have
nothing to do with subscriber identity. The value in the "User name"
field should only be used in the Authorization header. It is
completely unrelated to the identity of the caller. Is this a bug
being tracked?
Below is text from the
http://wiki.sipfoundry.org/display/xecsuserV4r2/SIP+Trunking page that
supports what was observed.
If the ITSP does not recognize this field and uses the From header for
account identification, these features may not work as expected. if
you select to "use default asserted identity", you must specify a user
name so that the default /Asserted Identity/ may be computed.
and as clarification, I think this is version 4.2.0 sipx.
from a 'sipx' itsp account setup, we have the account number and
password in the itsp account fields, the 'register on init' CLEARED.
The issues come in when a remote call come in, and is forwarded. the
callid that shows up on the phone that the call was forwarded to is the
level3 'user'.
